Speaker 2

Thank you, Kathy, and good afternoon, everyone. In the Q1, we exceeded the high end of our guidance for both revenue and earnings per share. We set a new record for datacom laser chip orders, including 200 gig EML chips, reflecting strong demand from multiple customers, including an AI infrastructure customer. Based on expanding cloud demand and improving trends in the broader networking market, we expect double digit sequential revenue growth in the Q2. During the Q1, we advanced our strategy to expand and diversify our cloud and AI opportunities.

Speaker 2

We secured an additional hyperscale transceiver customer with a new qualification and initial volume orders. This is beyond the new award we highlighted last quarter. We expect to start shipping volume production against these new customer awards in the first half of calendar twenty twenty five and they will ramp through the year consistent with the revenue targets we set out previously. Over the past few quarters, I outlined a 3 pronged strategy to grow our cloud data center business. As a reminder, the first prong is to expand our cloud and AI customer opportunities at the component and transceiver levels as customers migrate to higher speeds.

Speaker 2

The second is to scale significant production capacity for components and transceivers outside of China. And the third is to advance our differentiated technology roadmaps, enabling customers to scale future generations of cloud and AI data center architectures to higher compute capacities in a more cost effective and power efficient manner. I would like to share more details on recent progress in each of these areas. Regarding the expansion of our customer opportunities, as the industry transitions to higher speeds, our differentiated technology becomes increasingly valuable, especially to market and technology leading customers. For example, in the coming year, the transition to 200 gs lane speeds will drive growth and increase the importance of single mode optics and indium phosphide laser transmitters.

Speaker 2

This shift aligns well with our market and technology leadership. Our indium phosphide EML transmitters have established a strong reputation for high performance, high quality and reliability. Underscoring this, our 100 gs EMLs are currently shipping in high volumes to a wide range of optical transceiver suppliers for use in leading edge single mode 400 gs and more importantly, 800 gs optical transceivers. These customers are now designing our 200 gs EMLs into their next generation of transceivers, positioning us well for the upcoming transition to 200 gs per lane. We've also made significant progress in expanding our opportunities on the high speed datacom transceiver side of our business.

Speaker 2

As we previously forecasted, our datacom transceiver shipments are expected to increase sequentially this December quarter and we expect our transceiver production to continue growing throughout calendar year 2025 driven by demand from multiple hyperscale cloud NAI customers. As I mentioned earlier, we received an initial set of orders from new hyperscale customers and expect to start shipping production transceiver volumes for these new customers in the first half of calendar twenty twenty five. In addition, we are actively working to finalize additional awards for multiple other opportunities. The 2nd prong of our cloud and AI data center strategy is to expand our manufacturing capacity at established Lumentum facilities outside of China. This expansion is essential to ensuring a secure and reliable supply chain for our cloud and AI customers.

Speaker 2

Our indium phosphide laser chips are critical to data center infrastructure. As discussed in our last earnings call, to meet the growing demand, we are on track to increase EMO production capacity by 40% in Q4 of fiscal 2025 compared to our capacity in Q4 of fiscal 2024. This expansion will help alleviate the industry wide shortage of indium phosphide capacity. However, we still expect to be on allocation throughout calendar year 2025. Our Datacom transceiver capacity expansion at our Thailand campus is progressing as planned.

Speaker 2

The first production line is now operational and we anticipate completing additional expansion phases over the next 18 months to meet the high volume of demand from our customers. This includes completing construction of our new 3 story clean room facility on the same campus, which remains on schedule. The 3rd prong of our cloud and AI strategy focuses on delivering innovative technologies to address the escalating challenges of scaling data center compute capacity. We are collaborating with leading edge customers to develop breakthrough solutions to enable higher data link capacities with enhanced energy efficiency that will support their multi year cloud and AI infrastructure roadmaps. Inside the data center, optical switching is expected to be critical for future generation cloud and AI network architectures.

Speaker 2

Lumentum's power efficient, high bandwidth and low latency optical switches are well positioned to meet the demands of these evolving networks. We have already shipped evaluation units to customers who have provided overwhelmingly positive feedback on our performance. While we are beginning to ramp our 200 gs laser chips, we are already working in close alignment with customers on technologies for future generations of yet higher speed optical links such as 400 gs per lane and new architectures including co packaged optics, which will require unique ultra high power lasers. Our advanced indium phosphide and photonic integrated circuit capabilities are essential for meeting these upcoming demands. While we don't expect the deployment of these technologies to start until our fiscal 2026, we are actively collaborating with customers to shape the future of optical technology.

Speaker 2

Executing our 3 pronged strategy will drive significant revenue growth fueled by new opportunities in AI and cloud data centers. This growth combined with a recovery network business positions us to return to a double digit operating margin as our capacity utilization improves and we maintain strict cost discipline. As we outlined at the OFC conference last spring, we are targeting an operating margin of 17% to 20% once our quarterly revenue surpasses $600,000,000 per quarter. Now let me move to additional fiscal Q1 revenue and product highlights. Our Q1 Cloud and Networking segment revenue grew 11% sequentially and 23% year over year, driven in part by strong end market demand from cloud hyperscale customers as they invest within and outside of AI data centers.

Speaker 2

We are also encouraged by continued growth in shipments of our newest networking products. This combined with improving inventory levels of our products at our networking customers is encouraging as we look to the future. We had a sequential increase in demand for our narrow line with tunable lasers used in high speed long haul applications as well as 400 ZR and higher speed solutions in DCI applications. With our existing design wins in this area, we anticipate maintaining a leading market share in laser components for ZR and ZR plus applications this fiscal year and beyond. Customer interest in our advanced coherent transmission and next generation transport solutions is on the rise.

Speaker 2

In leading edge coherent transmission, we are experiencing robust demand for 130200 Gigabaud coherent products. This demand is driven by the need for greater capacity and spectral efficiency amid continued bandwidth growth. Our differentiated technology, manufacturing capabilities and strong design win momentum position us to maintain leadership in these critical products as well. Complementing growing demand for our coherent transmission components, we are seeing increased demand for integrated C plus L band transport solutions, high port count ROADMs and the emergence of demand for multi rail ROADMs and amplifiers. Multi rail is the next step in efficiently scaling the optical transport layer and offering increased flexibility in high capacity line systems.

Speaker 2

We anticipate strong sequential growth in our cloud and networking revenue in fiscal Q2 due to rapid growth in our products addressing cloud and AI applications and broad based improvement in demand across our product portfolio. Now let me move to our Industrial Tech segment. As expected, our Industrial Tech segment revenue grew 2% sequentially, while being down 38% from the same quarter last year. Like others in this space, demand continues to be challenged due to the weak industrial end market. In industrial tech, we are focused on developing innovative industrial laser products to meet customers' needs for higher precision with minimal heat damage.

Speaker 2

This creates opportunities for our ultrafast laser products in heat sensitive applications like semiconductors, displays and advanced packaging. We are working closely with leading semiconductor equipment manufacturers in interposer and advanced semiconductor packaging applications. We recently delivered high and low power femtoblade demo units for advanced display applications and we have received positive customer feedback. Looking to fiscal Q2, we expect Industrial Tech to be approximately flat sequentially due to an uptick in industrial lasers led by our ultrafast lasers offset by a sequential decline in 3 d sensing revenue. To summarize, we have made significant progress in executing our strategy to grow our cloud business.

Speaker 2

We set a new record for datacom chip orders and are working diligently to fulfill this demand over the next several quarters. We also made excellent strides with multiple high speed optical transceiver customer engagements, including securing meaningful transceiver orders from a third hyperscale customer. Additionally, we are actively working to secure more awards from more new customers. Our robust pipeline of cloud customer engagements combined with improving trends in the traditional networking market reinforces our confidence in achieving our previously stated target of growing quarterly revenue to $500,000,000 per quarter by the end of calendar year 2025. We anticipate continued significant growth into 2026 and 2027 as we capitalize on new cloud and AI opportunities, positioning our cloud business for a multibillion dollar annual run rate in the coming years.

Speaker 2

Before I turn the call over to Wajid, I want to express my sincere gratitude to our employees for their unwavering focus and dedication and to our customers worldwide for their partnership and collaboration. With that, Wajid?

Speaker 3

Thank you, Alan. Before I outline our Q1 financial results, please note that consistent with our discussion last quarter, we have changed our presentation to include certain charges that were previously excluded, primarily related to abnormal excess capacity in our non GAAP results starting in the Q1 of fiscal 2025. Comparable historical periods have been recast to align with this presentation for consistency. 1st quarter revenue of $336,900,000 and non GAAP EPS of $0.18 were above the high end of our guidance ranges. GAAP gross margin for the Q1 was 23.1%, GAAP operating loss was 24.5% and GAAP net loss per share was $1.21 Turning to our non GAAP results.

Speaker 3

1st quarter non GAAP gross margin was 32.8%, which was up sequentially and flat year on year on higher revenue. In future quarters, we anticipate company gross margins will sequentially increase as manufacturing utilization improves due to an improving telecom outlook as well as an increase in datacom laser shipments. 1st quarter non GAAP operating margin was 3%, which was up sequentially and year on year. 1st quarter non GAAP operating profit was $10,000,000 and adjusted EBITDA was $37,000,000 1st quarter non GAAP operating expenses totaled $100,400,000 or 29.8 percent of revenue, a decrease of $1,000,000 from the 4th quarter and down $1,900,000 from the year ago quarter. Despite increased investment in our expanding cloud opportunities, Q1 operating expenses were lower due to restructuring actions that were taken during fiscal 2024 as well as overall stringent cost controls across the company.

Speaker 3

Q1 non GAAP SG and A expense was $37,700,000 Non GAAP R and D expense was $62,700,000 Interest and other income was $4,600,000 on a non GAAP basis, driven by interest earned on our cash and investments. 1st quarter non GAAP net income was $12,200,000 and non GAAP diluted net income per share was $0.18 Our fully diluted share count for the Q1 was 69,100,000 shares on a non GAAP basis. During the Q1, our cash and short term investments increased by $29,000,000 to $916,000,000 Our working capital came in as expected with inventory levels increasing sequentially to support the expected growth in revenue across our cloud modules business. In Q1, we invested $74,000,000 in CapEx, primarily driven by investments in high speed transceiver capacity additions at our Thailand manufacturing site as well as indium phosphide wafer production capacity. Turning to segment details.

Speaker 3

1st quarter Cloud and Networking segment revenue at $282,300,000 increased 11% sequentially and 23% year on year. Cloud and Networking segment profit at 13% increased sequentially and year on year. Our 1st quarter Industrial Tech segment revenue at $54,600,000 was up 2% sequentially and down 38% year on year. 1st quarter Industrial Tech segment profit of 4% increased sequentially and decreased year on year. Now let me move to our guidance for the Q2 of fiscal 'twenty five, which is on a non GAAP basis and is based on our assumptions as of today.

Speaker 3

We expect net revenue for the Q2 of fiscal 'twenty five to be in the range of $380,000,000 to $400,000,000 This Q2 revenue forecast includes the following assumptions: Cloud and networking to be up sequentially with strong growth in products addressing cloud applications and improving networking customer demand and industrial tech to be approximately flat sequentially with increased industrial laser shipments offset by a decline in 3 d sensing. Based on this, we project 2nd quarter non GAAP operating margin to be in the range of 5.5% to 7.5% and diluted net income per share to be in the range of $0.30 to $0.40 Our non GAAP EPS guidance for the 2nd quarter is based on a non GAAP annual effective tax rate of 16.5%. These projections also assume an approximate share count of 69,600,000 shares. With that, I'll turn the call back to Kathy to start the Q and A session. Kathy?

Speaker 1

Thank you, Wajid. Now let's begin the Q and A session.

Operator

Our first question today comes from Samik Chatterjee with JPMorgan. Your line is now open.

Speaker 4

Hi. Thanks for taking my questions and congrats on the strong guide here. If I can just ask on the guide first, I think the implied increase quarter over quarter in cloud and networking is about $50,000,000 $60,000,000 quarter over quarter. Can you sort of parse that out a bit for us in relation to how much of that is telecom improving versus maybe datacom chips versus datacom modules, if you can directionally sort of point us to where most of that improvement is coming from? And I have a follow-up.

Speaker 4

Thank you.

Speaker 2

Sure. Thanks, Samik. This is Alan. I'd say it's a mix of all of the above. I'd say datacom chip growth is not a lot until the next couple of quarters because the capacity comes in increments and chunks.

Speaker 2

And so as I said in the script, the Q4 number will have a step up, but not a lot of chips increase this quarter. The telecom is modest and I don't expect that that to be strong growth other than things that are going into DCI applications, but there's a large pickup on the datacom modules and we expect that to continue as we said in the script through calendar 2025.

Speaker 4

Got it. Got it. And for my follow-up, you announced another sort of new customer win. Now you have I mean, if I take and aggregate the 2 new customers you've announced in recent quarters, how should we think about the magnitude of the opportunity maybe after a full ramp with both of them compared to what was the original customer for Cloudlight? How should we think about the magnitude relative to the first original customer there when we take the new 2 new customers together?

Speaker 4

Thank you.

Speaker 2

Yes. I think that's hard to answer in that it's going to come down to our ability to execute and provide the kind of quality and delivery and capacity that the customers need. So the new customers, as I said before, will start ramping in the first half of next year and it'll be ours to earn their growth of their business in the second half. And I think we're positioning ourselves very well. We're having the capacity in place, as I said, with clean rooms as well as equipment.

Speaker 2

So we're planning for success, but we still have to earn that. But that said, these are all very, very large customers that consume a lot of transceivers. And so getting in the door is step 1 and earning bigger share is really what we're striving to do now.

Speaker 5

Okay. Great. Thanks for taking my questions.

Operator

Our next question comes from Simon Leopold with Raymond James. Your line is now open.

Speaker 6

Great. Thanks very much. I wanted to dig a bit more into what's going on with the Cloudlight business. Reflecting back on when you reported your 3rd fiscal quarter last year, you had talked about sort of the cadence of that business where we'd see a bit of a pause in June September, which I think we've seen in sort of the snap back in December. And so what I'm trying to get an assessment of is sort of what's changed in that December outlook versus what you thought several quarters ago?

Speaker 6

Is it above, below? And what's different in terms of informing that expectation on Cloudlight? Thank you.

Speaker 2

Thanks, Simon. Yes, nothing has really changed. I think it's coming in as expected as we've talked about the transition of new products. We're ramping the new products now. And so it's kind of come together as we had expected and as we had talked about on our previous two earnings calls.

Speaker 2

So nothing unexpected from my perspective.

Speaker 6

And then just as a follow-up, I'd like to get your perspective on how you see the market for 1.6 terabit devices evolving and what you would anticipate your role would be in that market really sort of timing and magnitude perspective? Thank you.

Speaker 2

Yes. That one is a tougher one and that lots of interest from lots of customers for 1.6t. And in fact, it's kind of 1.6t is one version of the next generation of products. There's also 800 gig using 200 gig lanes. And so we're going to participate at the component level as I talked about in the script with our 200 gig EMLs and that ramps really more towards the summer of next year.

Speaker 2

But we're in the qualification stages today and have received volume orders today as our capacity is quite constrained. So we'll play it at the component level with EMLs and mostly and then we'll play at the transceiver level. We've sampled transceivers to customers and feedback very, very positive as we talked about on the last call. So we're in the hunt, we're in the game and we just need to continue to work on the qualifications. And then the timing is really up to the customers as well.

Speaker 2

So some are ready sooner than others, but I'd say that by the end of next calendar year, 1.6t should be ramping in a significant way.

Speaker 7

Thank you.

Speaker 1

Thanks, Simon.

Operator

Our next question comes from Meta Marshall with Morgan Stanley. Your line is now open.

Speaker 8

Thank you. This is Kwan Jivakar on for Meta. Just quickly and congrats on the quarter. I guess, are there any changes to your timeline for vertical integration with Cloudlight? I think you mentioned sort of no shipments until the end of fiscal 2025, but just sort of any updated timeline on your vertical integration there?

Speaker 2

No real change. I mean we're building products with our lasers and EMLs and VCSELs to be qualified. But I'd say the timing is really unchanged in that products that we were working on before the acquisition are coming to market now and those mostly didn't change. But I'd say that we have certainly opportunities in calendar 2025 to have more product in feeds and that should help margins late in the calendar year and into calendar 2026.

Speaker 8

Okay, that's helpful. And then a quick follow-up on the telecom side. Are you sort of expecting sequential growth primarily from new products or products that didn't previously had inventory build up? I think you mentioned that last quarter. I guess how do you expect sort of traditional telecom products to track and sequentially across the year?

Speaker 2

Thank you. Sure. I mean I'd say that we're seeing dramatic strength in anything ZR or anything to connect data centers as data centers are being built out and that can take the form of ZR modules. But given our share of tunable lasers that go into ZRs, that's where we're going to see a dramatic pickup in the telecom side. So I'd say that the hyperscale growth is very solid outside of the data center and that includes transport or open line systems.

Speaker 2

I'd say that carrier spending is still muted and inventory still needs to get burnt off there, but there are signs of light. So new products are flowing out the door as we talked about. And I think we're a quarter or 2 away from having return to more normal inventories, but we're seeing certainly good signs of inventory reductions of our product at our customers.

Speaker 6

Thanks, Bharat.

Operator

Our next question comes from Anadha Baruah with Loop Capital. Your line is now open.

Speaker 7

Hey, guys. Good afternoon. Thanks for taking the question. We just love to get your thoughts, Alan, on how to think about tariff positioning, tariff risk, hot topic kind of these days. So just your thoughts there in the context of diversifying out of China?

Speaker 7

And then I have a quick follow-up as well. Thanks.

Speaker 2

Yes. I don't think our strategy is changing based on who is going to be in the White House. We've been on a strategy to be a U. S. Headquartered company with manufacturing outside of China and that is not changing as a result of potentially increased tariffs.

Speaker 2

So I would say that it positions us very well as we've had an established manufacturing facility that we're growing dramatically in Thailand. And our laser chips come out of the U. S. As well as the U. K.

Speaker 2

And Japan. So from that perspective, I think we're as tariff free as you can get with respect to our future. So I don't think any strategy change is happening, but I'd say that that resonates with a lot of our customers who want to have supply chain resilience and we provide that for them both with vertical integration as well as a limited footprint in China and a growing footprint outside of China.

Speaker 7

That's super helpful context. Thanks. And then just a quick follow-up is just on EML lasers, given this constraint position, is there any, I guess, pricing power that you guys have or that you're using that you could flow through? Thanks. And that's it for

Speaker 2

me. I think we look at pricing on a portfolio basis and I think that as things are constrained, they go down slower or go up faster. And so I think in the constrained environment as we look forward, and as we sit here today, I think, we have to pay for a lot of capital that's going into add capacity. So I think that we're justified in looking at price optimization on EMLs is one area that we are looking at and have implemented some strategic pricing for those products.

Speaker 5

Operator?

Speaker 1

Yes, we are ready for our next question.

Operator

I apologize. My line was muted. Mike Genovese from Rosenblatt, your line is now open.

Speaker 5

Okay. Thanks very much. I guess, can I just

Speaker 6

ask for more color on the telecom market? And when you make comments about 2627 and that kind of visibility, is that all of the datacom side or how far does the telecom visibility extend?

Speaker 2

I mean, I think the telecom traditional telecom or carrier telecom, the visibility is not great. Although I would say that the deployments have been below the speed of bandwidth demand growth. And so there is going to have to be some additional spending deployments on new networks. And we're seeing that today in China as they're rolling out new networks. Visibility of telecom carrier network spending in 2026 and 2027, I'd be kidding you if I said I had good visibility to that.

Speaker 2

I think more so, the data center and the data center interconnect markets, we believe is going to be very strong in the future. And frankly, we have a fairly small footprint and small share of datacom transceivers. And with our U. S. Headquarter and manufacturing outside of China, I think there's a compelling reason for customers to come our way.

Speaker 2

So we expect to not only grow our datacom module business and EML chip business, but gain significant shares through the next coming years.

Speaker 6

Great. That's very helpful.

Speaker 5

And then finally, guess, can

Speaker 6

you give me more color on the optical switch product in the data center? Like what it's going to do in the data center? And is this kind of a completely new function? Or is it kind of like the next will it replace anything or replace part of anything? And I'm specifically thinking about Ethernet switches, whether there's anything there.

Speaker 9

Yes, Mike, this is Chris. Let me take a stab at that. It's performing, obviously, the name optical switching. And at there are, as you know, in a data center, there's a tiering multiple levels of optical switches to get the large scale that's needed, the connectivity across a very large data center. And so the ability to produce high radix, so 300x300 kind of level switches, I guess you could argue replacing some level of electronic switches.

Speaker 9

I think that a little bit more of the NAND in that it enables the data center to scale more efficiently, so that the power consumption that's in today's switches or the switches that you would use had you scaled today's architectures then can be used for more GPUs and more networking optics, etcetera, to interconnect AI accelerators. So that's really the idea here is that to bring a lot more energy efficiency when you're talking about big pipes going across a very large data center. The other advantage also to be clear is that as you add layers of switches, the switches do have added latency and optical switching has very little latency. So that's also a big advantage as you increase the size of data centers. Sorry, Mike, you were saying?

Speaker 6

Okay. Thanks so much. Well, I was just going to say, so basically it sounds like larger cluster sizes of GPU. As they get larger and larger, you need larger optical switches basically, just to sort of summarize.

Speaker 9

In general, yes. I think there can be other uses and maybe a couple of things to also point out that for us, this is a natural extension. It's leveraging the technologies that we've pioneered in the ROADM space over past several decades. And so it's really adapting of technologies that we've had to a new data center opportunity.

Speaker 6

Perfect. Thanks so much.

Speaker 1

Thanks, Mike.

Operator

Our next question comes from Tom O'Malley with Barclays. Your line is now open.

Speaker 5

Hey, guys. Nice results and thanks for taking the question here. So I wanted to understand the qualification process on the transceiver side. So you've now won another award and you talked last quarter about kind of qualification in the Q1 time period with that first customer. So can you maybe refresh us here?

Speaker 5

So 2 new customers, are both of them qualified yet? And when they are qualified, when do you normally get a feel for the volume that you're going to get? Obviously, being qualified and the amount that you actually end up shipping is a different thing, but you're very confident to next year. So just can you remind us when are these two customers going to be qualified? And then when will you have a feel for those volume forecasts for those customers?

Speaker 2

Yes. I'd say we're still on track with what we said last time with the first new customer that we talked about on the last earnings call with qualification happening in the 1st calendar quarter. I would say the new customer that we added this quarter is qualified now and we received orders now that will be beginning to ramp in the first half of next year. So a little bit different timing, but we're happy with both. And as I said before, we've got a lot of other qualifications going on that we'll talk about on the next earnings call, I hope.

Speaker 5

Super helpful. And then just looking at the moving parts to kind of get to that $500,000,000 a quarter, you guys have kind of expressed some increased confidence there, perhaps a little bit on that. So you're kind of in the low $300,000,000 a quarter right now. You talked about EML setting a record. I think previously you were $80,000,000 or so a quarter.

Speaker 5

So let's just assume a little bit above that. But you've kind of talked about capacity being outstripped for 2025, so you're basically sold out there. So when I look at where you go from here, the low $300,000,000 to kind of that $500,000,000 range, is more of that incremental the E and L lasers or is more of that incremental the qualifications of these new transceiver customers and they're ramping? Anything there would be really helpful. Thank you.

Speaker 2

Sure, Tom. I think starting with our midpoint of our guidance for our fiscal Q2, which is the quarter we just guided, we're guiding to 390s midpoint. And I'd say that there's a combination of what we expect to win and grow between now and the end of next calendar year. As I talked about in the script, growing EML capacity by 40% from the June quarter of last year to the June quarter of this year. This coming fiscal year is part of that growth, but I'd say transceivers are growing.

Speaker 2

Anything regarding data center interconnect is going to grow. And we're not counting tremendously on a bounce back in the traditional telecom business with carrier spinning. And if that happens then we'll get there sooner. But I'd say that's kind of the 3 big prongs which is growth in the chips starting really in the summertime, growth in transceivers that we've talked about really starting in the December quarter and then data center interconnect are really the 3 big drivers for getting us from 390,000,000 as a midpoint to the 500,000,000

Speaker 1

dollars Thanks, Tom.

Our next question comes from caller Ackerman with BNP. Your line is now open.

Speaker 10

Yes, thank you. I wanted to double click on the hyperscale win as well as the design win you spoke about last quarter. Specifically, are these transceiver opportunities being driven by hyperscalers or large customers connecting their own AI processors? Or is it being driven by you being included on reference designs of maybe perhaps new GPU platforms? And as you address that question, are these initial transceivers now integrating your EMLs?

Speaker 10

If not, does that push out the ramp of these customers or hyperscales ramping your optical products in 2025? Thank

Speaker 9

you. Yes. Thanks, Karl. I think we don't want to necessarily get into customer architectures and what they're deploying. But we can certainly comment on our transceivers.

Speaker 9

And so these in general are transceivers that won't have our EMLs at initial launch, if you will, because these have been in development and designed over the past year or so. Obviously, these accounts have other opportunities to Alan's point as we succeed and execute with them, not only will there be more share, but there will be more SKUs and other types of transceivers where we can introduce more of our own content.

Speaker 5

Okay. Thank you.

Speaker 1

Carl, did you have a follow-up?

Speaker 10

Yes. I guess, perhaps along the same lines then, could you discuss whether the new wins that you're receiving are driven by data center customers reallocating procurement of these optical transceivers to U. S. Domiciled suppliers like yourself? If you could just comment on that.

Speaker 10

And then perhaps in addition to that, are you able to quantify maybe the expanding TAM that you see as these AI clusters are now at the option of being disaggregating some of the components of scale up architectures? Are you also seeing that as a new opportunity? Thank you.

Speaker 9

Yes. So maybe add that these are new opportunities. So they're so it's not a reallocation. I would say that customers are certainly like the fact that we are U. S.

Speaker 9

Headquartered and non China manufacturing and a long roadmap of that. So I think that makes us more competitive in winning in these new opportunities. These are definitely scale out for the time being. The introduction of optics into more of a scale up is probably a year or a year and a half out kind of time frame. And there's certainly people making progress towards that.

Speaker 9

But these are traditional pluggable transceivers for scale out hyperscale opportunities as people deploy a lot more AI gear, if you will. If you recall that if you turn the clock back a year ago, there are really only 2 folks building AI gear. And I think you'll have more I think you brought up the word to an extent some level of disaggregated architectures as we roll forward into calendar 202526.

Speaker 1

Thanks, Karl.

Operator

Our next question comes from David Vogt with UBS. Your line is now open.

Speaker 11

Hey, guys. Thanks for taking the question. This is Brian on for David. Can you clarify if these transceiver customers were contemplated in your 4Q, 2020 5 guidance? And then I have a follow-up.

Speaker 9

4Q, 2020 5 guidance.

Speaker 1

End of.

Speaker 2

Yes, we talked about calendar 2025 and getting to $500,000,000 I think we have plenty of opportunities whether this one or that one was in our number. We don't need to win all the ones we're going after. So it's hard for me to say that, yes, we're right on track with these 2 that we had planned on. So I'd say that that's a hard one to answer. They certainly play a part in getting us there.

Speaker 2

And we're really, really happy with the progress we've made with these customers as well as other customers that we expect to be talking about on future calls.

Speaker 11

Got it. That's helpful. And then as for my follow-up, in the qualification process, you mentioned that you have to earn more volume. Does that mean you're a secondary provider in these deals? And then if so, what type of share would be reasonable in your view?

Speaker 2

Well, I'd say that in any of our businesses, we have to earn trust and earn share and that's done through quality execution and resilient supply chain and doing what we say we're going to do. And share does shift in all of our business as a result of performing well or not performing well. And so that's what I intended to mean by that discussion. I'd say that there are hyperscaler demand is very big and no one relies on one supplier. So as they ramp up 2 or 3 suppliers, the ones that perform better are going to get more share in the long run.

Speaker 2

So that's what we're really working on to make sure that we gain that trust and we gain that resilience of supply so that customers can count on us to provide more of their product that they need and that's what we're working on.

Speaker 1

Thanks, John.

Speaker 11

Thanks for the color.

Speaker 5

Sure.

Operator

Our next question comes from Ryan Koons with Needham and Co. Your line is now open.

Speaker 5

Great. Thanks for the question. I wanted to circle back to your comments around DCI and understand your exposure there on tunables. But can you maybe talk about what your opportunities in the module space there? Are you present?

Speaker 5

Do you have any design wins in ZR today for ZR modules? And how should investors think about that opportunity for the company?

Speaker 2

Yes. So DCI exposure, I would say the biggest revenue exposure for us is what I said before, which is the tunable lasers and to a lesser degree other components to go into other people's ZR and ZR plus modules. We do have exposure to our own ZR module and we're making very good progress on the 800 gig ZR and ZR plus both domestically as well as outside of the U. S. So we're favorably encouraged by the progress there.

Speaker 2

I'd say the 400 gig module, frankly, we were late to market. We have small share and we're doing our best to try to gain share there. But frankly, the market is very, very strong and we're very happy in growing our tunable laser business there and supporting our customers who are winning significant share in a market that's growing very rapidly as data centers are moving further apart.

Speaker 5

Yes, that makes sense. It's more of a mature market there. And then a quick question for Wajid around gross margins and kind of in lieu kind of a lot of puts and takes going on here. How should we think about gross margins as the fiscal year unfolds here?

Speaker 3

Yes. Thanks, Ryan. So like we talked about in the script, we're expecting gross margins to improve sequentially. We're even seeing it in Q2. You can see that our operating margin profile is significantly different than what we how we performed in Q1.

Speaker 3

And so we're expecting to see that gross margin improvement move into Q3 and into Q4 as well as more of our supply comes online for EMLs. Having said that, we are expecting to increase our R and D spend in Q2 and into Q3 and Q4. You can probably tell from Alan's comments that customer pull is quite strong and the opportunities are quite strong as well. And so because of that, we're probably going to be spending ahead of revenue from an R and D standpoint. And we've already talked about some of the capacity investments we're making.

Speaker 3

So yes, we'll see gross margins tick up sequentially through the fiscal year, but we'll it will be muted a little bit from an operating margin standpoint because of the increased R and D investment we're making, just given the amount of customer pull we have.

Speaker 7

That's great. And does that capacity

Speaker 5

you just talked about adding does that capacity you talked about, does that have an overhead impact also a little headwind there until it's fully Yes,

Speaker 3

it does. Thank you. Yes, thank you. No, it does have a little bit of overhead impact because we're building out in our Thailand facility as we move more of our production of transceivers to Thailand. And so as we move that up and ramp that up, there will be a couple of quarters of overhead expenses associated with that.

Speaker 3

And so that's already contemplated in the sequential increases in margins. But then as that volume ramps up in the middle part of next calendar year, we'll be able to see the benefit of that moving through the quarter. So, we'll explain more about that as the quarters happen, but thank you for asking about that.

Speaker 5

Sure. That's helpful. Thanks a lot guys.

Speaker 1

Thanks, Ryan.

Operator

Our next question comes from Christopher Rolland with SIG. Your line is now open.

Speaker 12

Hey, guys. Thanks for the question. So Alan, I wanted to double click on your prior answer around vertical integration in the lasers in particular into Cloudlight. You said it mostly didn't change. Wanted to know what actually did change there.

Speaker 12

And then you suggested the second half of twenty twenty five for those margin benefits. So I would assume that's a timetable for integration. And perhaps I may have been wrong here in my assumption, but my assumption is that you would be more meaningfully integrating in the first half. So I'd love to know is this a qualification issue? Is this not a delay?

Speaker 12

Was this just my understanding that's wrong? Is this EML constraints? What exact is that timetable pushing out indeed a bit for vertical integration and what's causing it?

Speaker 2

Yes. So good question, Christopher. I'd say a couple of things, one of which is customers don't want us to change product that's already in flight. That's number 1. Number 2, our laser capacity is constrained.

Speaker 2

So we have to make make versus buy decisions around what mostly the product going through the transceiver business today is silicon photonics based. So we use a lot of CW lasers, not EML lasers yet in the products that we're shipping and released today. So we can buy those CW lasers externally or we can use our very critical EML capacity to add those CW lasers into our products. We've done the math. There's a lot of good CW laser suppliers.

Speaker 2

It makes more sense for us to buy those CW lasers and free up that EML capacity to ship to our customers than it would be to convert that EML capacity to CW lasers, for example. So that's one of the things that's pushing off that integration of CW lasers into our products until the second half. I'd say that we are working on EML based designs and those will come to market in the second half of the calendar year. We have to get qualified and go through that. But today, most of the products that we're producing are silicon photonic based, using CW lasers from our strategic supplier partners to keep that EML capacity for our customers.

Speaker 2

Yes. And I'd add that the real So

Speaker 9

our So our natural roadmap also aligns with using more vertical integration where the technologies are much more differentiated at those speeds.

Speaker 12

Thank you very much, Guy. That actually cleans up a lot for me, clears up a lot at least. It also probably brings me to my second question, which is trying to understand more about EMLs. I mean, it just seems like the whole market is moving here, AI demands inflecting units. There's one other big EML player as far as I've recognized at least.

Speaker 12

It seems like if you have this EML capacity available, it actually has pull into your transceiver units, pipeline, market share, customers, new customers, etcetera. So

Speaker 6

why

Speaker 12

are we talking about 40%? Like why aren't we talking about like 100% or even more here? Why is 40% the right number here? And like how capital intensive is this? If you wanted to like how fast could you get new lines up?

Speaker 12

And would you be leaning on overbuilding versus underbuilding just given what seems like the importance of this part into this new cycle? Thanks.

Speaker 2

Christopher, you sound a lot like my Board of Directors. So that's a very good question. It does take time to add capacity. One of the things that we did as we were working on integrating and giving synergies, we had 2 wafer fabs in Japan. We were going to close one of them consolidated.

Speaker 2

We stopped that several quarters ago and said we need that extra wafer fab capacity and we're ramping that up now. If you go back a year and a half ago, we had idle capacity in our wafer fab. It takes a year and a half to add capacity. So that's kind of what's going on. We are adding more.

Speaker 2

We're converting to larger wafer sizes. That takes time. And we're adding epi reactors that takes time as well. So very good question. If I had the ability to add 100% between now June, I would do it.

Speaker 2

But that's the lead time of capital equipment and bringing up and qualifying new tools is just painful. But the good news is there's barriers to entry in that market. And so we're going to grow it as fast as we possibly can. And at the same time, we're going to introduce new products. And so that 200 gig per lane, it's new product, we're getting qualified.

Speaker 2

That takes time and resources and starts typically at a lower yield. And we have to get through that learning curve and that yield. And so I think we're going to do well in the second half of the calendar year on that. But we are adding capacity beyond the 40% for sure after the June quarter. We're not sitting idle for sure.

Speaker 12

Perhaps just one more follow-up. Why don't you use your Sure. Okay. Thanks, Kath.

Speaker 3

Okay. I was just going to

Speaker 12

say why don't you use your limited EML capacity to bring new cloud like customers online? It seems like that would be 2 birds, 1 stone.

Speaker 2

Yes. That's a good question. I think we have silicon photonics, we have multimode VCSEL based transceivers and we have EML based transceivers. We are designing each of those for a given application. Some applications work better with single mode silicon photonics.

Speaker 2

Some have a better cost structure with EMLs. And as Chris said, a lot of the new next generation of 1.6 gs likes EMLs better, especially as you get into multi wavelengths where EMLs can really play a key role there. So yes, we're absolutely going to do that. It probably makes more sense in the second half of the calendar year as we get into these more advanced 1.6 t products. And then we have next generation 200 gig EMLs, which are really going to differentiate us from our competitors.

Speaker 2

And I think that really gives us the ability to drive incremental differentiation at the transceiver level and drive higher gross margins.

Speaker 12

Thanks guys. Sorry for the 3rd question.

Speaker 1

Thanks, Chris. Sierra, I think we'll squeeze in one more question.

Operator

Understood. Our final question today comes from Richard Shannon with Craig Hallum. Your line is now open.

Speaker 9

Glad to get in

Speaker 13

under the wire here. Thanks for taking my questions guys.

Speaker 4

I feel a follow-up on

Speaker 13

the topic of the optical circuit switching here is a couple of earlier questions and comments. Maybe you can just kind of delineate the timeframe for qualification and volume ramps here just to get a sense there. And then also your maybe your close peer who reported recently has obviously talked about a product necessary. Maybe you can discuss how you're differentiated or different or complementary to what they're doing?

Speaker 2

Yes. I can tell you about what we're doing. I can't really comment on what they're doing. I'm sure their technology is unique and interesting. I think our technology and our approach is different.

Speaker 2

Ours is MEMS based and we have as Chris mentioned earlier years of experience with MEMS designs and MEMS in our WSSs. In fact our most advanced WSSs have multiple technologies like LCOS and NIMs. So we are getting positive feedback as we said from our customers. There are customers that are more advanced and more ready to put optical circuit switches into their data centers and then there's customers that need to re architect or write software to enable this optical circuit switching. And so it's really dependent upon which customers are ready when.

Speaker 2

But I would say that a deployment in calendar 2025 is realistic. And really the more meaningful growth will probably be in calendar 2026.

Speaker 13

Okay. That's great detail. Thanks for that, Alan. My second question

Speaker 5

I was just going to add

Speaker 2

one thing, Richard. We've already transferred the product to our Thailand operations. So we're making qualification units and beta units in Thailand today. And so we'll be ready when the customers say go.

Speaker 13

Okay, great. Thanks for that, Alan. My second question is on a topic that has been asked in a while and that's 3 d sensing. Is there anything going on here either in your kind of past markets or new markets here that's going to give us any signs of growth and improvement anytime soon?

Speaker 9

Hey Richard, this is Chris. I would say a little bit of yes and a little bit of no. I would say that obviously the high volume applications that we have been playing into for several years is mature and there's not an obvious catalyst in that specific application other than if the Android world begins to adopt in mass. No suggestion that they will in the short term or midterm, but that's always a possibility. I would say as we look to other opportunities in sort of metaverse, augmented virtual reality and applications like that are helping a bit as well as the automotive space, but both of those have been a little slower to adopt than we've all hoped.

Speaker 9

But there are folks continuing to invest strongly in that. And as a leader in the technology, we continue to partner with those leaders. But we'll keep things muted in terms of thoughts on that until that new application really comes along.

Speaker 1

Thanks, Richard. Great.

Operator

Thank you, guys.

Speaker 1

Thanks, Sienna. Yes, thank you. Sienna, I think we'll pass the call back over to Alan for some concluding remarks.

Speaker 2

Great. Thank you. I'd like to leave everyone with a few thoughts as we wrap up the call. We are excited about our growth prospects, our comprehensive photonics portfolio built on differentiated in house technology and proven manufacturing capabilities addresses critical challenges like connectivity bottlenecks and power consumption. With strong progress on these 3 on our 3 pronged strategy, we are highly confident that we will reach $500,000,000 in quarterly revenue by the end of calendar 2025 and in the long term expand our cloud business to a multibillion dollar annual run rate.

Speaker 2

Thank you for joining our call today. We look forward to seeing you again at investor conferences and upcoming meetings this quarter. Have a great day.

Operator

That will conclude our conference call today. Thank you all for your participation. You may now disconnect your line.
